Hi Grazyna,
That Lumix is quite handy, they have something in their tones I like, maybe is the Leica connection with Lumix, I am not sure, I also like the feel of Fuji imaging too. This feels like film, I could easily be fooled into thinking as such as the grain feels natural, random, when most digital noise looks ordered and artificial, this looks right. Mostly, I love the image, the distortion, the expressions, they seem almost..sheepish, like they are slightly shy..very cool shot.
Cheers
Justin

I'm so glad I found this photo. I love bubbles in photos and this kind I have not seen before in B&W. I love the composition and artistic POV. Light management is perfect and reflection off of bubble is great. Excellent job Grazyna!!

TFS..............Buddy

PS. I just posted a photo with bubbles as well with waterfall, maybe you will find it pleasing?
